Grid of invention description (out). The x-y punch 33 and the planar stator 15 form an electromagnetic linear stepping motor 152. Commercially available linear stepper motors are available from > jorthern Magnatics, Santa Clarita, California. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the xy punch 33 includes two sets of single cymbal heads and permanent magnets installed at 90 degrees, which can hold the punch 33 holder against the stator (not shown) ). A compressed air supply 54 supplied by the compressor 110 is supplied to the x-y punch 33 when the model manufacturing equipment 30 is operated. The compressed air supply 154 flows upward through the x-y punch 33 and flows out from an upper surface, as shown in Fig. 6B. This outflowing air forms a £ air bearing 156 'between the x-y punch 33 and the planar stator 150, which allows the clock head to perform nearly frictionless movement on a horizontal surface under the planar stator 150. The driving signal sent to the x_y punch 33 is received via an electrical supply 158 which activates a stepper motor driver (not shown) in the x-y punch 33 to achieve the movement cycle. Often, this type of linear stepping motor can exhibit sudden, transient movements that cause mechanical vibration. This resonance typically excludes such motors from applications in high-precision systems, such as rapid prototype systems. As described below, an umbilical connected to the head has amazing results for providing sufficient damping to allow high-precision deposition at high speeds far exceeding speeds possible in the rapid prototype system of the prior art. . The mold manufacturing extruded arm 34 is a flexible chain carrier that is flexible on the horizontal y-plane and rigid in other directions. The arm 34 carries an air supply 154 and a punch electrical supply 158 therein. The arm 34 also carries a model manufacturing extrusion head electrical supply 160 and a flexible air tube 162 therein. The air tube 162 contains a weekly garden air supply and model making. Page 18 This paper is applicable to China. Standard (CNS) M specification (2ι〇 · χ297 mm) 411313 A7 ------------ B7 V. Description of the invention () ~~~~ —— Make filament 4 0 'as shown in Figure § City in a picture. The arm 34 and the air supply 154 'punch electrical supply 158' extrusion head electrical supply 160 and air tube 162 together form an umbilical member 163 connected to the extrusion head 32. The umbilical member 163 buffers the mechanical vibrations of the extrusion head 32 relative to the stator 30 due to the acceleration and deceleration of the head 32 by the punch 33 and produces surprising results. In the preferred embodiment, the combined weight of the head 32 and the x_y punch 33 is less than or equal to 8 pounds. For small oscillations, the frequency of resonance is about 55Hz, and for large vibrations, the frequency of read vibration is about 45Hz, and the damping time to reach 98% of the final value in this embodiment (which is approximately equal to the damping time) 4 times the constant) is less than or equal to 150 microseconds. The mechanical oscillation and damping can be expressed as: A = A〇sm (w t + φ) et / T 'where A = amplitude, a 0 = amplitude that is initially undamped, w = 2 7Γ f, f = resonance of the system Frequency, Hu = a phase constant, time, T = damping time constant. The critical damping occurs at τ = 〖/ ω. In the preferred embodiment described, the system is critically damped by about 10 times. So 'can add further damping if needed. This damping time constant is affected by the combined weight of the head 32 and the χ-y punch 33. The lighter the weight, the shorter the damping time constant. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics The damping of mechanical resonance is mainly achieved by the friction generated during the movement of the umbilical i 63. Alternatively, other damping mechanisms may be used, such as an oscillating diffuser (or shock absorber) incorporated in the extrusion head 32. And 'further damping can be generated by reducing the impact resistance of the stator 150 (for example by using copper instead of steel) to increase the full current loss in the stator 150.

The model making material and the base material are selected so that the model making material is completely adhered to the base material. When an object is formed, the model making material is deposited on a substrate in multiple layers. The support material is then deposited in one or more layers on the child model making material. Then use multi-layer model manufacturing materials and / or supporting materials to develop the object on the supporting material. When the object is completed, the object is destroyed by lifting a corner of the substrate 60, and then the substrate will be damaged by the operator. It is removed from the platform 62. By bending the substrate 60, the operator can tear the substrate 60 from the object.
